We have two. People complain they stop working; we bought two and had to almost immediately return one but since we got the new one we've had ours for more than a year and they keep going. They do get dusty so require periodic cleaning
. We also found that unless you keep them running all day, you cannot get them to turn on at night... maybe the motor
requires too much juice from the battery.
They work well but do not expect them to cool the cabin
- they are just to move some air.
We put one in the shower
stall of the head
and another in our cabin
[but not above the bunk]. So if either develops a leak or seawater gets through it will just go into the bilge
